I'm having a table problem with my K2 Items and Categories.

I used jUpgrade to update joomla and k2 and tthen I followed up by upgrading k2 (twice now to 2.5.5)

first problem was that k2 menu items became unwired, open and saving seemed to fix that.

remaining problem is that I can edit/save or create new k2 items. Getting the following error.

Joomla!
500 - An error has occurred.

Table 'datxxx_dbxxx.a86c3_finder_types' doesn't exist SQL=SELECT `id` FROM `a86c3_finder_types` WHERE `title` = 'K2 Item'

Please help, I'm stuck.

If you do not use the K2 Smart Search you can safely disable it to fix the problem.

joomla admin > Extensions > Plugin Manager > Disable "Smart Search - K2" plugin.
